Problems solved by technology
Nevertheless, problems may arise when the individual separate web rolls have reached their selected diameter, and it becomes necessary to transfer the web sections from the completely wound separate web rolls over to new roll cores.
The path from the cutting location at which the web sections are cut, to the individual winding positions is of different lengths, thereby causing potential problems.
Therefore, the individual web sections must be separately manipulated many times, a procedure that is complicated and cumbersome.

Abstract
Method and a device for winding web sections into web section rolls. The device for winding web sections into web section rolls comprises a central roll and a cutting section. The web section rolls rest against the central roll in at least two winding position groups that are axially offset from one another at different positions about the circumference of the central roll. The cutting device axially extends axially over the winding position groups, and is adapted for pivoting about the central roll through the winding position groups. The method of winding web sections into web section rolls comprises cutting a web section at the point where a web section roll contacts the central roll and transferring the cut web sections to new roll cores.
Description
The present application claims priority under 35 U.S.C. .sctn. 119 of German Patent Application No. 198 01 874.6, filed on Jan. 20, 1998, the disclosure of which is expressly incorporated by reference herein in its entirety.1. Field of the InventionThe invention relates to a method and device for winding web sections into web section rolls, and more particularly, to a method and device for winding web sections into web section rolls which rest against a central roll in a number of winding position groups axially offset from one another in different circumferential positions. When the web section rolls reach a selected diameter, the web sections are cut and transferred to new roll cores.2. Discussion of Background InformationPaper webs today are frequently produced on paper making machines where working width is greater than the width desired by the users in printing facilities and the like. In one of the last manufacturing steps, paper webs must be cut to the desired width and then ...
